Calendars, to-do lists, journal entries, and contacts, synced over the open CalDAV and CardDAV standards nearly every client already speaks: Radicale is a small pure-Python server that works with Thunderbird, DAVx5 on Android, Apple Calendar and Contacts, GNOME, and many more. Its defining design choice is radical simplicity: there is no database. Events live as plain .ics files and contacts as .vcf files in an ordinary folder structure, which makes backup a copy command, migration a move, and disaster recovery a matter of reading text files. The server works out of the box with no complicated setup, then grows as needed: flexible authentication (htpasswd files among other methods), per-collection authorization rules, TLS-secured connections, and a plugin system for extending storage, auth, and rights handling. Built-in limits on parallel connections, file sizes, and failed authentication attempts harden it for network exposure behind a reverse proxy. A bundled web interface handles creating and managing calendars and address books - useful since many clients cannot create collections themselves. Maintained since 2011 with 140+ contributors, GPLv3-licensed, and light enough to run on the smallest VPS or a Raspberry Pi.

ODS turns a GPU machine or server you already own into a complete private AI stack with a single install command, replacing a shelf of separate tools with one system that serves models, chat, agents, automation, and search from your own hardware. The installer reads your GPU, VRAM, memory, and disk, then downloads a GGUF model matched to that hardware tier, and a compact bootstrap model starts answering within minutes while the full model finishes downloading. From the web dashboard you watch every service's health, ports, and resource use, restart what misbehaves, and check storage and updates without touching a terminal. You chat with local models in Open WebUI, hand background work to the Hermes and Portal agents, and build automations in n8n that connect the stack to more than 400 other apps. Documents you add become searchable knowledge through Qdrant vector storage, so answers cite your files instead of the model's memory. SearXNG and Perplexica answer web questions without trackers or accounts, Whisper transcribes speech, Kokoro reads text aloud, and ComfyUI generates images, all on the same box. Every bundled service is an extension you can enable, disable, or replace, and a Privacy Shield scrubs personal data before anything reaches an optional cloud model through the LiteLLM gateway. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Roughly $1M of development work, open-sourced: Maybe Finance began as a $249/year commercial personal finance product before the company released it all. It aggregates bank accounts, credit cards, loans, investments, crypto, and real estate into a single net worth dashboard with historical trend charts - replacing the spreadsheet that usually glues a whole portfolio together. Transactions are categorized and tagged with rules, with merchant tracking and search across imported or synced activity; budgets track spending by category against plan; and the investment view follows holdings, cost basis, and returns across brokerage accounts. Multi-currency support converts accounts held in different currencies into a single reporting currency, bank synchronization works through Plaid where supported, and manual CSV import covers any institution. An optional AI assistant answers questions grounded in your own financial data. Because the app was built as a paid product with professional design before being open-sourced, its interface quality exceeds most community finance tools - and self-hosting means your balances and transactions are not monetized by a free app or gated behind an annual subscription. The stack is Ruby on Rails with Hotwire on PostgreSQL, licensed AGPL-3.0 and deployed via Docker. The original repository is archived; development continues in the community fork Sure, compatible with the same self-hosted setup.

Hister is a private search engine for everything you have read or saved, indexing the full text of visited pages, local files, and imported browser history so one query finds the page you only half remember. Firefox and Chrome extensions capture each page as you browse, while a crawler and importers for browser history and bookmarks backfill earlier reading. Watched directories add local files to the same collection. Queries accept field filters, quoted phrases, wildcards, negation, date ranges, and aliases, with a readable stored preview beside each result. Opt-in semantic search matches documents by meaning through an Ollama, llama.cpp, or OpenAI-compatible embeddings endpoint. The same index answers in the browser, a terminal interface, the command line, an HTTP API, and an MCP server for AI assistants. Multi-user mode gives each person separate documents, rules, and access tokens, with password or OAuth sign-in, and public mode lets anonymous visitors search a curated index. Rebuild a research trail, recover a half-remembered article, or share one searchable knowledge base, with no telemetry.

Your photo library belongs on infrastructure you control, encrypted so thoroughly that the server itself cannot peek, and that is exactly how Ente stores every picture and video you back up to it. Phone, desktop, and web clients encrypt each file on the device before upload, so backups, live photos, and videos arrive as ciphertext that only your keys can open. The browser app gives you the full library from anywhere: timelines, albums, favorites, a map of geotagged shots, and memories resurfacing old trips. Shared albums let family members add photos, comment, and like each other's shots, all still encrypted end to end. Collect links flip the flow around, giving wedding guests or clients a single link where they can drop their own photos into your album without creating an account. Face grouping and semantic search run on your devices, so you can find "beach sunset 2023" or every photo of a person without a server ever seeing the images. Duplicate detection and cleanup suggestions reclaim storage, exports download your entire library in open formats whenever you want it, and multiple accounts on one instance let a household share the same server. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

No cookies, no fingerprinting, no cross-site tracking, no personal data collection - Umami's privacy contract is the foundation of the open-source web analytics platform. IP addresses are hashed rather than stored, which makes it GDPR, CCPA, and PECR compliant by default - the consent banner can come off the site entirely. The tracking script is under 2 KB, roughly 20x smaller than Google Analytics, so measurement stops being a page-weight tax. The dashboard covers the core metrics - pageviews, visitors, bounce rate, visit duration, referrers, browsers, devices, and countries - with any date range and filtering by country or device. Beyond pageviews, custom events track clicks, form submissions, and signups via a data attribute or one JavaScript call, and advanced reports add funnels, user journeys, retention and cohort analysis, goals, and automatic UTM campaign tracking. Anonymous session views show individual visitor activity without identifying anyone. Teams share websites with role-based access, one instance manages unlimited sites, and a full REST API exposes every metric programmatically. MIT-licensed and self-hosted on PostgreSQL or MySQL via Docker, your analytics data never leaves your infrastructure.

Redlib lets you read Reddit without an account, ads, or trackers, through a clean page served from a machine you control. Open any subreddit, user profile, or comment thread and the server fetches the content and relays every image and video itself, so your browser never talks to Reddit directly. Pages need no JavaScript, unless you opt in to HLS video playback with sound. Choose card, clean, or compact layouts, a wide interface, and one of more than a dozen themes, from Dracula and Nord to Gruvbox and Tokyo Night. Post and comment sorting, a search box scoped to the current subreddit, a wiki tab, and subreddit filters help you find and tame your feed. Subscriptions build a personal home page with no login. Spoilers and NSFW previews can be blurred or hidden, and an SFW-only mode blocks mature content for the whole instance. Optional RSS feeds let a feed reader follow subreddits. Links to removed posts open in a configurable undelete viewer. Operators set defaults through environment variables, add an instance banner, discourage search indexing, and route outbound traffic through an HTTP or SOCKS proxy. Settings live in a browser cookie and can be exported or imported between devices. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

CRM mechanics applied to your actual relationships instead of a sales pipeline: Nametag is a Personal Relationship Manager (PRM). It exists to fix the things you keep forgetting: when you last talked to an old friend, their kids' names, the birthday you missed twice. Contacts are tracked with flexible attributes - names, birthdays, important dates, and free-form notes for everything else - and organized into custom groups. Where it goes beyond a contacts app is relationship mapping: you define how people connect to each other (family, friends, colleagues, or custom relationship types), and an interactive D3.js-powered graph renders your entire personal network so you can see clusters and connections at a glance. Staying in touch is automated: scheduled reminders fire for birthdays, important dates, and reach-out nudges, with optional email delivery via a Resend API key for password resets and reminder notifications. Built with Next.js, it is mobile-responsive, ships with full dark mode, and supports multiple languages including English and Spanish. Because it is self-hosted, there are no account tiers or contact limits - unlimited people and relationships, with every note about your personal life stored on your own server rather than a social-graph company's cloud. A lightweight, single-container deployment makes it one of the easiest personal tools to run.

One article should not require a subscription, an account, and your tracking consent. 13ft is a self-hosted alternative to the defunct 12ft.io that fetches web articles the way a search-engine crawler receives them, then shows you the clean page without paywall walls, ad clutter, and pop-up nonsense attached. Paste a link into the single input, or better, install the companion bookmarklet: one click on any article page rewrites the address to your own server, and the reading copy comes back from infrastructure you control. Because it is yours, there is no third-party service logging every article you read, no central site that can be taken down and strand the habit, and nobody selling a premium tier of unblocking. It handles the stubborn cases with a loading page and multiple fallback retrieval methods that kick in when the first approach fails, ships localised interface strings in several languages, and the whole thing is one small application that runs from a container and sits politely behind a reverse proxy. Casual readers reclaim the occasional long-form piece; researchers and archivists get a reproducible way to fetch the same copy a search index saw.

SnappyMail is a fast, privacy-respecting webmail client that connects to any existing IMAP and SMTP server, booting in under a second with a JavaScript payload of just 138 KB under Brotli compression (down from RainLoop's 8 MB fork origin). No database is required: all configuration and user data persists as flat files in a single volume, making Docker deployment trivially simple with the roughly 30 MB image consuming approximately 50 MB of RAM. Built-in PGP encryption supports three backends: OpenPGP.js v5 with ECDSA and EDDSA key generation, GnuPG integration, and Mailvelope browser extension compatibility, eliminating the need for separate encryption plugins. The integrated Sieve script editor enables users to create mail filtering rules, vacation auto-responders, and forwarding conditions directly within the web interface when connected to ManageSieve-capable servers on port 4190. Multi-domain administration allows a single instance to serve users across multiple IMAP servers with per-domain authentication routing. The admin panel manages extensions, security settings, branding customization, and domain configuration. GDPR-friendly by design, it removes all social media integrations, Gravatar lookups, and external tracking present in RainLoop. Dark mode strips background and font colors from email messages. The modified Squire HTML editor replaces CKEditor for composing rich-text messages. Scores 99% on Lighthouse performance.

Most proxies ask the operating system nicely for a socket; paqet skips the conversation, building its own TCP packets byte by byte to tunnel traffic between your machine and your server. The server end listens on a port you choose and speaks only in raw packets it crafts and captures itself through pcap, before the kernel's connection tracking ever sees them. On your machine, the client presents an ordinary SOCKS5 proxy on localhost plus optional port forwards, so browsers and command-line tools connect exactly as they would to any proxy. Between the two ends, KCP with smux multiplexing turns a stream of self-contained packets into fast, reliable, encrypted sessions, with AES or lighter modes selected per deployment. TCP flag cycling varies how packets present themselves on the wire, giving operators control over the traffic pattern the tunnel produces. Built-in utilities generate the shared secret, ping the server with a single test packet, and dump live traffic decoded, so a silent tunnel gets diagnosed in minutes rather than by packet-capture archaeology. One YAML file per side declares the role, network interface, gateway MAC, and keys, and the same binary runs both ends. It suits security research, hostile networks, and anyone whose ordinary proxies keep getting reset.

Real-time alerts from your own infrastructure to your phone, with no Firebase, Pushover, or third-party push service in the path: Gotify is a simple, self-hosted notification server written in Go. The model is deliberately minimal: senders push messages with a single HTTP POST to the REST API, receivers subscribe over a WebSocket stream, and a clean React web UI manages the pieces. Senders are namespaced as "applications," each with its own token, so your backup script, Uptime Kuma, CI pipeline, and cron jobs each get an identity, an icon, and independently revocable credentials - centralized alerting from many services with per-source management. Messages carry a title, body, and priority level that maps to notification importance on the client. The official Android app (on both F-Droid and Google Play, notable for working entirely without Google Play Services) shows push notifications for new messages; the web UI itself supports Web Push in the browser; and gotify/cli pushes messages from shell scripts with one command. A server-side plugin system adds custom behavior, and the whole thing runs as a single small binary with SQLite by default - near-zero resource footprint. Because dozens of tools (and Apprise) speak Gotify natively, it slots in as the notification hub for an entire homelab or ops stack.

Every account you run deserves its own browser identity, and FoxProfile keeps those identities permanently separate instead of letting them bleed into one another. Create a profile once and it remembers its device: screen, GPU, CPU cores, fonts, and canvas noise are generated on first launch and reused on every later one, so the fingerprint a site saw yesterday is the fingerprint it sees tomorrow. Sessions stick too: history, cookies, and logins live in the profile directory, and the tabs you left open reopen where you left them. Each profile carries its own proxy (HTTP, HTTPS, SOCKS4, or SOCKS5, with a built-in checker) while timezone and locale follow the exit IP automatically or stay pinned to your choice, and the Check IP button compares the exit address across three services and flags mismatches or datacenter addresses. Cookies move in and out as standard editor JSON or Netscape files, whole profiles travel as ZIP archives, and bulk actions launch, stop, or delete fleets at once. On a server, the web panel runs profiles headlessly so you can manage them and view their screens from anywhere, the REST API scripts everything, and the MCP server lets AI agents drive the browsers directly.

MiroTalk C2C is a self-hosted WebRTC cam-to-cam calling server that turns one private link into an encrypted one-to-one video call in the browser, with nothing for guests to download or sign up for. Create a room, pick how you want to join, and share the room ID: the other person opens it and you are face to face with video, audio, and screen sharing between desktops and phones. Push-to-talk and best-quality toggles sit next to camera, microphone and video quality controls in the in-call settings, and session time stays visible so lengthy calls never surprise you. Replace your background with the built-in Off, Blur, or Image modes processed locally in your browser, and show your camera as a picture-in-picture bubble in a corner of a shared screen so presentations keep a human face. The meeting is private by design: you choose the room and how you join before entering, and media stays encrypted between participants. Host it with the official Docker image on your own infrastructure to keep media and signaling under your control, embed calls into your own products with the direct room join and REST API, and use ngrok support for quick testing. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Website analytics, uptime monitoring, and server status - three tools most teams run separately - combined in Tianji, an open-source observability platform. The analytics layer tracks page views, unique visitors, referrers, and UTM parameters with a lightweight cookie-less script, which keeps collection GDPR and CCPA friendly. The uptime monitor checks availability and latency on configurable intervals, accepts passively reported results, and publishes public status pages for incident communication. Server status agents report CPU, memory, disk, and network metrics with threshold-based alerts, and notifications route through webhooks, Slack, Telegram, and other channels with noise control. It also includes anonymous telemetry for tracking deployments of your own open-source projects, surveys, waitlists, team collaboration, and an OpenAPI interface for integrations and exports. The consolidation is the point: traffic analytics, uptime checks, and server metrics share one interface and one alerting layer, so diagnosing an incident does not mean hopping between Google Analytics, Uptime Kuma, and Prometheus - and the built-in public status pages replace a separate paid Statuspage-style subscription. Because collection uses no cookies with IP truncation and aggregation by default, basic traffic measurement requires no consent banner. Built in TypeScript under the Apache 2.0 license and inspired by Umami and Uptime Kuma, it is deliberately right-sized for independent developers and small SaaS teams whose monitoring needs are real but lightweight.

Nojoin takes notes on your Meet, Teams, and Zoom calls without sending a bot into the meeting: it records from your browser and transcribes on your own server. Nothing extra joins the call and nothing announces itself to the room; you meet as usual, press record, and the browser captures the audio. Transcription runs locally with Whisper or Parakeet, so the audio never leaves your hardware, and speaker recognition matches voiceprints across calls, so a person you name once is labelled correctly in later meetings too. AI notes can come from an API provider, your existing Claude or ChatGPT subscription, or Ollama on the same machine for fully local processing. During the call, Meeting Edge suggests questions, flags points you may have missed, and explains unfamiliar terms in real time. Afterward, analytics measured from the audio report talk-time share, turn-taking, and overlapping speech. A built-in MCP server hands Claude or ChatGPT 32 tools over your library, 19 of them writable, so an assistant can search every meeting, correct a misheard line, turn action items into tasks, and reconcile attendees with your CRM. Google and Outlook calendars sync automatically, every meeting carries its own chat, and finished notes export to PDF, Word, or plain text. Stored credentials are encrypted with a key you control, and anonymous telemetry can be switched off entirely. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Large link collections stay fast and organized in Faved, a private, self-hosted bookmark manager built for exactly that job. Its core is a nested tagging system that outgrows flat folders: place Go and Python under Programming Languages, color-code tags, add descriptions, pin frequent ones to the top of the sidebar, and optionally roll up child-tag items into parent views. Saving is frictionless - a lightweight bookmarklet works in any desktop or mobile browser without extensions, and Apple devices can send links through the native Share menu. Faved fetches titles, descriptions, and preview images automatically, keeps that metadata fresh over time, and flags duplicates as you save. Instant as-you-type search, flexible sorting, and bulk actions (retag, delete, refetch) keep collections of any size manageable, while customizable layouts - card, list, or table - plus a system-synced dark mode adapt the interface to your workflow. Migration is first-class: import from Chrome, Safari, Firefox, or Edge with folder structure preserved, or move from Pocket and Raindrop.io keeping tags and collections. The stack is deliberately light - PHP 8 with SQLite behind a React/Tailwind frontend - deploying via Docker with no external dependencies. All data stays local: no ads, no tracking, and no risk of your library vanishing with a discontinued service.

Up to 280 search services - Google, Bing, DuckDuckGo, Brave, Qwant, Startpage - aggregated without tracking or profiling: SearXNG is a privacy-respecting metasearch engine (AGPL-3.0, successor to Searx). Your instance queries the upstream engines on your behalf: your IP address, cookies, and search history never reach them, tracker parameters are stripped from result URLs, and an optional image proxy fetches thumbnails server-side so result pages leak nothing. It can even route outbound queries through Tor for full anonymity. Search is organized into categories - general, images, videos, news, maps, music, IT, science, files - with bang shortcuts for targeting specific engines, and every source can be enabled, disabled, or weighted per category in settings.yml. A plugin system adds calculators, hash tools, tracker removal, and unit conversions inline, and preferences (themes, safe search, languages, engine selection) persist in cookies rather than server-side accounts. The real argument for running your own instance rather than trusting a public one is control: you decide the logging policy (none), the engine mix, rate limiting, and who gets access - making it the default search backend for browsers, families, and teams that want Google-quality results without the profile.
